Limited Knowledge of Rules: Lack of understanding of Arabic writing rules and conventions can contribute to errors. This includes knowledge of letter positioning, punctuation, and spacing.

Confusing Similar-Looking Letters: Some Arabic letters look very similar but have different shapes or dots (e.g., ب and ت). Confusing these letters can lead to errors.

Incorrect Letter Formation: Arabic letters have specific shapes and strokes, and writing them incorrectly can lead to mistakes. This often happens due to a lack of familiarity with the correct form of each letter.

Improper Connection of Letters: Arabic script involves connecting letters within words. Mistakes can occur if the letters are not connected properly, or if the shape of the letter changes incorrectly depending on its position in the word.

Ignoring Diacritics: Diacritics (Harakat) are crucial in Arabic for indicating vowel sounds and pronunciation. Omitting or misplacing them can lead to misunderstandings or incorrect meanings.

Lack of Practice: Insufficient practice with writing Arabic letters and words can result in inconsistent or incorrect letter formation and connections.

Forgetting Letter Variations: Arabic letters change shape depending on their position in a word (initial, medial, final, or isolated). Forgetting these variations can lead to mistakes in writing.

Influence of Other Scripts: If a person is used to writing in another script, such as Latin or Cyrillic, it may influence their Arabic writing style, leading to mistakes.

Handwriting Style: Variations in handwriting style can lead to inconsistencies in letter formation and legibility. Different styles may not always adhere to standard forms.
